So I notice that Nismo is making 5.89 gear sets for the H233B that's in the rear of my pathfinder - hooray!
:party0010:
The thing is, I wonder about the reliability of my gear sets at that low a ratio. I have a waggy D44 in the front, an axle I'm sure many more of you are familiar with. Has anyone had issues with breaking/stripping D44 pinions with 5.89's or are they as solid as any other ratio? I've heard that when you get to a certain point, ratio wise, the pinion winds up with so few teeth that it's inevitably weak.
Opinions???

:dontknow: id also be wondering about the nissan rear that low 5,29s in toyotas is as low as i would go
in my hi pinion d44 front striped several sets of 488s
but did same to d 60 rear:confused0006: to much skinny pedal:dontknow:
was in a heavy fullsize
you are right on not enough tooth contact think it would be low at5,89 and prone to breakage
shure would crawl good[cheers]
oh not shure on ring gear dia toy is 8 in think d44 is 8 1/4

i wold be a bit sceptical about running gears that low.
i wonder how much tooth engagment there is.

please don't use dana 44 and reliability in the same sentance .....they dont go well together[31]

I am sure it would be reliable for mall crawling

Anyone know the R&P tooth count - 5.89 vs 5.14? I can't go any higher than 5.14's without loosing my decent crawl ratio so if the pinon has the same amount of teeth in each range then I guess that would answer my question...

So, if the 5.89's have 9 teeth on the pinion, wouldn't it be stronger than the 5.38's (which I can't match my rear end to anyway) and, more importantly, 5.14's (which are available)? I'm thinking the pinion is generally the weak point rather than the ring gear, so this makes sense to me. Does the ring gear become compromised once it gets to "toothy"?

tooth count is irelevantits the contact of the gearsthe steeper the gear the less contact you wind up with all the load on 1 tooth its got more to do with diameter of pinion gear than any thing what gears does pathy run?? they might hold up in a light weight rock buggy but a heavy full body trail rig seems unlikely i could be wrong they make steper gears for toyotas and no one recomends steeper than 5.29 the nissan and toy rears are comparable size

I'm pretty sure Pathy runs 5.38's - he's got a 9" in the rear instead of the h233B but he runs a D44 front...

What yea got in ur transfer case for ratio??

id comprimise crawl ratiio a bit for gear set strength
was looking at pathys thread on his transfer case swap ouch that almost what i have into my whole truck
well maybe not nice stuff im runing a marlin krawler in my toy what a difference

this is correct, however, normally you can't run a 5.38 in the 9". you have to run 5.37 or 5.42.
i have a HI9, which haqve the 5.38 gears.

Even when i had the stock T case it was wheelable.
just a little had on the clutch in the rocks.

with 36" tires, to get back to stock ratio you would run 5.13, the 5.38's give you a little bit lower gear. (i assume your rig is standard, if auto you will be i even better shape)

So, since 5.38's are not an option (there's none available for the H233B), you're sayin' that I'd be better of to go with 5.13's over 5.38's? I want to get AT LEAST my stock crawl ratio with 36's, beyond that, I'm more interested in strength than ratio.

I would.

you running manual or auto tranny?

the problem with the 5.89 is the size of pinion. even though there are more teath, they are smaller teeth = less strength

then definately go with teh 5.13/5.14 combo.

I would if it was my choice.

If you need gears I bring in Nismo shit from japan it might save you a few bucks

give the brother a quote for some 5.13 gears for a nissan H233B rear end.

them gears are NOT cheap

Thanks for the advice Jeremy, I'm not much of a cowboy anyway so I'm sure it will hold up to my mild abuse. For the first year or so I'll be sportin' the 33's so I'll get a bit better gearing for awhile and less chance of breakage. Probably a good way to get used to my "new" rig...

actually, i wasn't stupid on any of the breaks.
however, 2 of them were with warlord.
